3M E-A-R UltraFit Corded Earplugs 25dB

These reusable earplugs deliver a 25 dB noise reduction rating with a patented triple-flange design. The no-roll insertion method allows users to push the plugs in by holding the stem, keeping tips clean even with dirty hands or gloves. Supplied as 100 pairs in a poly bag, they suit industrial environments such as construction, manufacturing, mining, oil and gas, and transportation.

Workers needing washable.

The corded design keeps the pair together during breaks and reduces loss on busy sites. The soft polymer material can be washed and reused, lowering replacement frequency and waste. Buyers who require single-use disposable plugs, higher attenuation ratings, or uncorded models for use with certain helmets should consider alternatives.

Check compatibility with 3M E-A-Rfit validation

Confirm that your fit-testing equipment supports these earplugs if validation is required. Ensure the universal size fits the intended users, as no alternative sizes are included. Verify that the 100-pair quantity matches your inventory planning and that the poly bag storage meets your site hygiene standards.
